| Popis: | Shot peening is a mechanical surface treatment that is used to improve material performance. The velocity of the shots is a significant parameter of the shot peening process, but it is not used as a controlled parameter by the shot peening industry. The present article establishes a framework for predictive modeling of shot velocity. The predicted shot velocities were in good agreement with published experimental results. The present results clearly show that once the shot material and its size are known, the velocity shot depends directly on Almen intensity. For a given combination of shot size, material, and peening angle, an increase in Almen intensity involves an increase in shot velocity. As a further demonstration of the capabilities of the proposed approach, we have found a relationship between Almen intensity and shot velocity. |
